Pale-leaved Wood Sunflower
Flowering heads have from 8 to 15
ray flowers surrounding a central cluster of yellowish disc flowers.
Involucral bracts are narrowly lance-shaped, and taper to a fine
point. Leaves are broadly lance-shaped, and are arranged in pairs,
except on the upper part of the stem, near the flowering heads,
where they may attach individually. Leaves are up to 22 cm long
by 6 cm wide, and have three prominent veins which emerge from
a common point near the leaf base. The upper surface of the leaf
is sandpaper-like, but stems are smooth. Leaf margins have inconspicuous
teeth at intervals of 0.5 to 1.0 cm. Flowering heads occur in
clusters that branch from the main stem. Found from July into
September, in woodlands and woodland edges. Helianthus strumosus
differs from H. tuberosus in having smooth rather than
rough stems. Native to N. A.
